6.4.1 Application Association Model
This section describes the gateway’s implementation of IEC-61850-72- Clause 7:
Application association model. This clause describes how the association
between two devices is achieved: TWO-PARTY-APPLICATION-ASSOCIATION
and/or MULTICAST-APPLICATION-ASSOCIATION. Both types are used.
Two Party Messaging
Two Party messaging is the most common type of messaging our IEC 61850
driver performs. The following diagrams show the execution of two-party
messages, and their associated abort sequence. In the diagrams, the IEC 61850
Client driver is the Client. This information has been taken directly from the IEC
61850 standard.
